Specification of Letters Patent.

Patented June 23, 1914,.

Serial No. 725,947.

To all whom it may concern:

Be itknown that 1, CHARLES A. NELSON, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention consists, in a novel combination of instrumentalities whereby the firing mechanism, normally disposed. to require such degree of movement of the releasing means for its firing member as is consistent with safety in ordinary handling of the arm, may be quickly and readily set to such a condition as to require any less degree of movement of the releasing means.

In the accompanying drawing, Figure 1 is a side elevation of the improved arm; Fig. 2 shows the parts directly involved in the invention on a larger scale, the frame appearing in longitudinal section; Fig. 3 is a horizontal sectional view in a plane just above the sear in Fig. 2; Figs. 4 and 5 are rear and side elevations of the trigger; Figs. 6 and 7 are underneath and top plan views of the setting lever; and, Figs. 8 and 9 are side elevations of said lever.

The frame a, breech-bolt 7) containing the spring-pressed firing-pin c and movable under the influence of the controlling lever (Z to perform the functions assigned thereto in the patent to A. W. Savage No. 491138, the sear 6 pivoted to move in the frame in a vertical plane and having a stop-face f to engage the firing-pins stop-face 9 arranged substantially perpendicular to the path of travel of the firing-pin, and the trigger it pivoted in the frame are or may be all substantially the same as in the said patent to Savage, except as hereinafter indicated.

The sear e is normally pressed upwardly in position to efiect the cocking of the firing pin by the spring 2' coiled around the pin j on which the sear is fulcrumed, one end of such spring engaging the sear and the other a stop 7:. The pin Z on the other end of the sear bears against the straight under face at formed at the upper end of the pivoted trigger, thus holding the trigger normally with its shoulder n bearing against the fixed stop 0, in which position the trigger is further held by the plate spring 3) bearing against the upper side of its grip end 9.

Fulcrumed on the pin 1" affording the fulcrum for the trigger is a lever 8 one arm 8 of which is curved downwardly to form a grip directly behind but spaced from the grip (7 of the trigger and the other arm 8 of which extends forwardly, substantially horizontally. The material of the members /z and a above their grip portions and on their adjoining sides is removed, as indicated best in Figs. 4, 6 and 7, so that when said members are assembled face to face with each other their grip portions (1 s will stand the one directly in front of the other, as stated above.

Tapped into the frame under the arm 8 of lever s is a set-screw a. By adjusting this screw up or down the range of movement of the lever 8, whose arm 8 may move into contact with said screw, may be varied.

At the back of the grip g of the trigger is a heel or lug o overhanging the ledge or shoulder to formed at the upper end of the grip s of lever s. The normal position which the scar and firing pin assume when the gun is cocked being that shown in Fig. 2, in which position their stop-faces overlap to the extent shown in said figure, it requires relatively appreciable movement of the trigger to move the sear sufliciently to release the firing pin. If the operator has occasion to require less movement of the sear to clear it from the firing pin he presses on the arm 8 of lever 8, whose shoulder to comes against the trigger at the lug 'v and so moves the trigger 'until the arm 8 of said lever impinges against the set-screw u; thus operating through the trigger, lever 8 causes the sear to be depressed to an extent predetermined by adjustment of set-screw u, the sear being held in the new position by the frictional action of the stop-faces f 9 held against each other by the firing-pin spring and the trigger and lever returning under the pressure of spring 29 as soon as the op erator removes the pressure of his finger from the lever arm 8. The degree to which the sear may thus be shifted in the direction to release the firing pin may be adjusted to suit the operator by turning the set-screw u and thereby altering the limit it affords the lever s in its movement. After firing and recocking, the parts assume the normal position.

Having thus fully described invention,

WhatI claim and desire to secure by Letters Patent is:

1. In combination With the frame, the firing means and means to retain the latter in cocked position, one of said means being movable in Wiping contact With the other to clear the firing means from the retaining means and thereby release the firing means means for advancing the said movable means toward the position to release the firing means including a trigger for moving the movable one of said means clear of the other means and a trigger moving device, and a stop limiting the movement of said device short of that necessary to move said movable means to the position to release the firing means. 7

2. In combination with the frame, the firing means and means to retain the latter movable in Wiping contact With the other to clear the firing means from the retaining means and thereby release the firing means,

means for advancing the said movable means toward the positlon to release the firing 25 means including a trigger for moving the movable one of said means clear of the other means and a trigger moving lever, and a stop limiting the movement of said lever short of that necessary to move said movable means to the position to release the firing means. v In testimony whereof I affixmy signature in presence of two Witnesses.
